    U suck I can't see the video

    What about same shade square. what type of illusion is this.
    What is the material of square?

    Yes, the refractive indices of the glass and glycerol are the same :)
    As light enters glass (or water) it slows down, in doing so it changes direction.
    Think of a straw in a glass of water. The light is bent as it enters and exits the water, and you see the straw in a different apparent location.
    Since the indices in this experiment are the same, the light passes through the glass and oil unphased, and it appears to VANISH!

    If you don't fill the inner bottle with glycerin, then you have a volume of air, with a lower refractive index, and it destroys the illusion.

    I saw something like this on Beakman's World when I was little. It was a little bit different though. The inner vessel was filled with water and the larger outer jar was filled with light cornsyrup. Something about the way light refracts through it makes the inner glass appear missing.

    Doesn't this happen because the index of refraction is the same on both the bottle and the water?

    Wow.  I had no idea that was possible.  Very interesting!

     hmmm interesting, why does this happen? does the glycerin have the same refracting properties as the glass?

    not sure, But I think it's also necessary to fill the inner bottle with glycerin.
